This is veru helpful. We are not using Dell OEM Package.
I was simply planning on running;
esxcli software vib install -d /vmfs/volumes/datastore1/update/ESXi510-201404001.zip
but according to this article it is recommended that I use the update command instead via;
esxcli software vib update -d /vmfs/volumes/datastore1/update/ESXi510-201404001.zip --dry-run
And the . --dry-runto get an output report is a great tip as well.
Thanks again.
